The amount of time spent explaining the use of the abacus itself could be considered an ´epilogue´ in back of the book and is completely in error with very poor examples for its operation. It is a shame that this book is still on the market. I do NOT recommend this paperback in spite of the free -- somewhat small -- abacus..

St. Martin´s Griffin claimed The abacus is as useful and effecient a machine today as it was when it was first created centures ago. Whether you´re an expert in the latest computer technology or you´re mastering arithmetic and word problems for the first time, it won´t take long to learn the basics (and even the not-so-basics) of adding, subtracting, multiplying, and dividing on this ingenious and fun-to-use mathematical tool.
